Editors’ Review
MSI Afterburner is a graphics card tuning software that provides direct access to GPU configuration, monitoring, and performance adjustment tools. It supports graphics cards from all major brands, allowing modification of clock speeds, voltages, and fan curves through a unified control interface. The software integrates real-time hardware monitoring, an on-screen display, and video capture.
MSI Afterburner features an OC Scanner for automated overclocking, enabling precise parameter control and data tracking. This combination of configurable tools establishes a complete environment for analyzing, tuning, and documenting GPU behavior under various workloads. It lets you save and switch custom profiles for different scenarios.
Overclock like a pro
MSI Afterburner allows precise modification of GPU clock frequencies and voltages through adjustable sliders. This functionality grants direct access to the card’s performance states, giving you control over GPU frequency scaling and power limits. The included curve editor visualizes the voltage-to-frequency relationship, letting you manually shape performance profiles. Undervolting optimizes power by reducing voltage at fixed clock rates, lowering heat while maintaining stable operation under heavy workloads.
The OC Scanner tool automatically tests and applies optimal overclocking settings for supported GPUs. It evaluates the GPU’s stability threshold and applies calculated values within safe operational margins. Alongside this, real-time hardware monitoring continuously displays metrics such as temperature, usage, clock speed, and fan speed. Readings display in an in-game overlay (OSD), powered by RivaTuner Statistics Server (RTSS), for continuous data tracking without leaving the application.
The software supports custom fan profiles, enabling manual or curve-based control of cooling behavior. You can define multiple fan response points, aligning cooling with thermal conditions for better temperature consistency. The included Predator module records gameplay or benchmarks using the H.264 codec. Recordings offer adjustable frame rates, resolution, and audio. However, manual data interpretation is required for tuning. These functions work regardless of GPU brand, ensuring uniform control.
Pros
- Supports GPUs from multiple manufacturers
- Includes automated overclocking via OC Scanner
- Integrated video recording with H.264 support
- Customizable fan speed curves and profiles
Cons
- Manual data interpretation required for tuning
Bottom Line
Unified GPU management platform
MSI Afterburner integrates overclocking, monitoring, fan tuning, and screen capture into a single platform for complete GPU control. Its primary function is to expose configuration parameters directly while displaying real-time performance data. The inclusion of an OC Scanner and video capture tool extends its scope beyond tuning alone. It offers extensive control but lacks advanced automation or predictive analytics, relying on user adjustments and manual metric interpretation.
What’s new in version 4.6.6
- Enhanced hardware monitoring capabilities
- Minor stability and interface refinements
